Glass tube temperature or current cut out

[tytower]

I have a switch pulled from a battery charger because it was broken . It is marked DL-01LL with something like a Mitsubishi badge after it . I think it is a current cut off at a certain temperature or flow .

I want to replace it but have not been able to identify it properly .
Can anyone suggest what I should be looking for ?

which is all I can read of it . I think it is a current cut off at a certain temperature or flow .

Photo would be good.
Rated current for the charger?

Guess would be a self resetting thermal fuse.

Thanks -Poor photo but charger is 10 amps

Thermal fuse, non resettable.

This will likely fit, and will be around the right temperature to protect the transformer.

Is this battery charger old?  I've seen old self-resetting circuit breakers that look like that.

True, but those have a visible metal strip inside that is the thermal sensor, and a small magnet that provides the spring force to reclose the contacts when it is cool enough, so they snap together and pop apart very fast so there is no arcing. They are very visible, and in this one you just have what looks like a a single shot with a thin element that has melted and pulled the 2 wire ends apart.

Yes its pretty old - maybe 10-20 years  thanks it used to reset . The metal strip disconnected and is loose in the tube now . Definately needs resetable on a battery charger.
